Scientists from Xi’an Jiaotong University in Liverpool have discovered that microbes can adapt to the effects of cleaning and industrial products, making the urban environment more suitable for the former. Research results It was published In the journal Microbiome.
The team of scientists collected 738 microbiome samples from various locations in Hong Kong (subways, residences, public institutions) and from human skin. Analysis using metagenomic sequencing revealed 363 previously unknown species of microorganisms. Some have adapted to using industrial products, such as cleaning products, as sources of carbon and energy. One such species, Candidatus Eremiobacterota, was previously found only in desert soils in Antarctica.
One of the authors of the study, Xian Jiaotong-Liverpool University associate professor Tong Such microbes may compete against less resistant strains, posing a health risk, especially if the microorganisms are pathogenic.
Additionally, 11 new strains of Micrococcus luteus have been identified, which may pose a serious threat to immunocompromised people, especially those in hospitals. Toon emphasized that these strains can contribute to the development of hospital-acquired infections, which can have a mortality rate of up to 30 percent in intensive care units.
In addition, the researchers identified two new species of Patescibacteria, called “nanobacteria”, characterized by small genomes. One of these strains found in human skin has genes for the synthesis of antioxidants such as carotenoids and ubiquinone, indicating a mutually beneficial relationship between bacteria and humans.
Scientists emphasize that understanding the metabolic functions of these microorganisms will help create healthy microbial ecosystems in urban environments and prevent possible health risks.
